Biomass gasifiers are equipment’s that can generate producer gas which is a renewable, alternate source of energy that can be employed for power generation and thermal applications. In this experimental study the gasifier is tested in updraft and downdraft modes and performance analysis was carried out. For both the studies, casuarina wood and ambient air were used as feed stock and gasification agent respectively. From the experimental analysis it was inferred that the performance of the biomass gasifier was higher in downdraft mode than updraft mode.

Rice husk is the waste from agriculture industries that has high potential to produce heat and electricity through the gasification process. Air suction mode is new development for updraft rice husk gasification, where blower are placed at output of gasifier. The objective of this research is to examine these new configuration at several equivalence ratio. The equivalence ratio was varied at 32% and 49% to study temperature profile on gasifier, producer gas volumetric flow rate, composition of producer gas, producer gas heating value, cold gas efficiency and carbon conversion. The time needed to consume rice husk and reach an oxidation temperature of more than 700oC for equivalence ratio of 49% is shorter than 32%. Producer gas rate production per unit weight of rice husk increase from  2.03 Nm3/kg and 2.36 Nm3/kg for equivalence ratio of 32% and 49%, respectively. Composition producer gas for equivalence ratio of 32% is 17.67% CO, 15.39% CO2, 2.87% CH4, 10.62% H2 and 53.45% N2 and 49% is 19.46% CO, 5.94% CO2, 0.90% CH4, 3.46% H2 and 70.24% N2. Producer gas heating value for equivalence ratio 32% and 49% is 4.73 MJ/Nm3 and 3.27 MJ/Nm3, respectively. Cold gas efficiency of the gasifier at equivalence ratio 32% is 69% and at 49% is 55%.

Abstract The researchers around the globe are trying to overcome energy crisis by developing suitable alternative energy source. In this work, combustion and performance analysis of a diesel engine was studied running in dual-fuel mode using producer gas. The experiment shows lower engine performance like brake thermal efficiency, increased brake specific fuel consumption and exhaust gas temperature in dual-fuel run as compared to diesel alone run. Combustion characteristics like cylinder pressure, mass fraction burned, mean combustion temperature and net heat release were also found to be deteriorated in presence of producer gas. The peak value of cylinder pressure and net heat release were noticed slightly away from the top dead center. The experimentation indicates that combustion improving techniques should be employed to enhance the performance of the dual-fuel engine to run with producer gas.

Rice husk gasification developed as process that converts organic rice husk into a producer gas. The achievement is to reduce dependency on fossil fuel, reduce pollution and move into green technology. Downdraft gasifier is a reactor that can produce lower tar concentration in the producer gas. There are important objectives had been investigated which are to modify on laboratory scaled downdraft gasifier from the previous project, where suitable with the rice husk gasification system, to measure the exit temperatures in gasifier which it determine tar quantity at the output, to measure the amount of moisture removed from the rice husk where it determine the quantity of moisture in rice husk and, to measure the complete burning of rice husk in a gasifier by taking the time performing the experiments. All the objectives are to be obtaining the output which can be used as a biofuel sources. The method to achieve the objectives, firstly redesign performed using SolidWork software. Next, the temperature determined using thermocouple. Then, next objective which the rice husk drying analysis determined by drying rice husk and scale it with weighing scale. And lastly, burning was determined by using stopwatch and weighing scale with complete fabricated gasifier. The results shows the fabrication of the modification, average exits temperature of producer gas which around 203.93°C, different moisture weight of rice husk which around 10grams and, average time of completes burning of gasifier is 61 minutes and ability to capture producer gas’s flammability. This work concluded by achieves the objectives based on the results and may increase in understanding of the works related.
